Yang Dingtian flew towards the light.
He found that although it looked very close, it was actually very far, more than a few hundred miles away.
After flying closer, Yang Dingtian was certain that this was the Mystic Meridian Essence.
Wu Youming's research was completely correct.
This Profound Vein Essence was indeed a kind of energy life. Because some kind of tear occurred in the world, the energy exchange between the surface and the earth's core completely relied on these Profound Vein Essences.
However, this Profound Vein Essence was completely different from Yang Dingtian's imagination.
In Yang Dingtian's impression, the Profound Vein Essence should be similar to the human body's veins. At most, it would not exceed three to five feet, which was dozens or hundreds of veins.
But in fact!
The Profound Vein Essence in front of him, he didn't know how long it was. It could be tens of thousands of meters, hundreds of miles, or thousands of miles.
In short, its top was connected to the Yin Yang Mirror's heavy water, and its bottom was connected to the depths of the earth's crust.
Moreover, its number was completely endless. Even Yang Dingtian didn't know how many veins there were, but it was definitely not less than thousands or tens of thousands of veins. In short, this was an extremely complicated system of veins.
At this time, each Profound Vein Essence was shining with a mysterious light. He could clearly see the energy coming and going, and the light inside was shuttling back and forth.
Of course, what Yang Dingtian didn't know was that the Profound Vein Essence collected by his master, Dongfang Minmie, was indeed only a few feet long.
Because the classification of the Profound Vein Essence was perhaps even more exaggerated than the human's Profound Vein.
The Profound Vein Essence could be divided by age, and also by energy level.
Divided by age, there were dozens of years, one or two hundred years, one thousand years, and ten thousand years.
Divided by energy level, it could be a Profound Vein Essence born in a mountain, or a Profound Vein Essence born in a lake.
Then what was the level of the Profound Vein Essence in front of him?
Only God knew.
Perhaps the Profound Vein Essence existed for as long as the Yin Yang Mirror existed.
Not only that, these Profound Vein Essences were born in the Yin Yang Mirror.
So no matter from which perspective, the Profound Vein Essence here was undoubtedly the highest level. Its level had even exceeded the knowledge of human martial artists.
Since he found the Profound Vein Essence, the next step was to collect it!
How to collect the Profound Vein Essence?
His master, Dongfang Minmie, had once taught Yang Dingtian this.
This was an extremely complicated process!
It was no less complicated than the most complicated surgery.
It was very simple, all he had to do was remove the Profound Vein Essence from the node.
This node was the root of the Profound Vein Essence. As long as he kept it, he could grow a brand new Profound Vein Essence in the future.
But at the same time, you must not break any of them, and you must not destroy any of the energy flow inside.
The Profound Vein Essence was extremely powerful and could withstand extremely powerful energy attacks.
However, it was very, very fragile. As long as the energy circulating in it leaked out, as long as the energy dried up, it would immediately wither and turn into ashes in an instant.
Therefore, Yang Dingtian had to remove them from the nodes one by one, but he couldn't destroy the energy flow inside.
Very quickly, Yang Dingtian found the node of the Profound Vein Essence. It was an energy ball of light. It was inside the heavy water, and countless Profound Vein Essences were growing from it.
Because the Profound Vein Essence ignored any physical damage and could withstand extremely powerful energy damage, it was impossible to cut it off. It could only be removed from the nodes.
Seeing the densely packed Profound Vein Essence on the nodes, Yang Dingtian's scalp went numb. There were at least tens of thousands of them, and each of them were intertwined with each other, forming a very, very complicated circulatory system.
Yang Dingtian took out a Thousand Year Owl's demon core from his bosom. For a long time, this demon core would temporarily replace the role of the nodes and act as the energy circulation center of the countless Profound Vein Essences.
Next, it was time to test Yang Dingtian's speed.
He took a deep breath, and then he started!
"Whoosh whoosh whoosh whoosh whoosh …"
Yang Dingtian's speed was truly fast to the extreme.
Using Profound Qi energy, he pulled out the Profound Vein Essences from the nodes one by one, and then quickly inserted them into the Thousand Year Owl's demon core.
His speed was completely insane. There were at least dozens to hundreds of them per second.
There was no other way. He had to be this fast. Otherwise, these Profound Vein Essences would be damaged.
Every Profound Vein Essence's opening was exposed to the vacuum for no more than a hundredth of a second.
Of course, as long as it was not more than a tenth of a second, it would be fine.
But Yang Dingtian could do it ten times.
These Profound Vein Essences directly drilled into the Owl's demon core as soon as they touched it.
That's right, the extremely hard Thousand Year Owl's demon core could not be pierced even by the Bloody Black Gold Sword.
These soft Profound Vein Essences could be easily drilled in.
Then, he continued to exchange energy with the Owl's demon core.
The Profound Vein Essences were extremely heaven-defying. As long as it was energy, it could do it, no matter if it was strong or weak, and no matter what attribute it was.
Just like this, hundreds of Profound Vein Essences were extracted every second.
…
After a full five minutes, the collection of Profound Vein Essences was completed.
These five minutes were an unprecedented five minutes for Yang Dingtian, and it was also the most tiring five minutes.
His Profound Qi and spirit were almost completely exhausted.
After the last Profound Vein Essence was pulled out from the node, suddenly …
"Whoosh …"
The more than thirty thousand Profound Vein Essences suddenly shrank.
One by one, they broke away from the depths of the earth's crust thousands of miles below and became only three feet long.
This scene was incomparably mysterious and incomparably gorgeous.
Previously, tens of thousands of Profound Vein Essences were thousands of miles long, but when gathered together, they were dozens of meters thick.
In an instant, they shrank to only three feet long and as thick as an arm.
However, it was still a complete energy circulation system!
The reason why it shrank to such a small size was because the energy it needed to transmit had shrunk countless times.
Previously, the energy transmitted and circulated was a full tenth of the Yin Yang Mirror, but now it only needed to circulate a demon core.
Although this was a Thousand Year Owl's demon core, it was only a tenth of the Yin Yang Mirror's energy, not even a millionth.
"Boom, boom, boom …"
Suddenly, the entire Yin Yang Mirror shook violently.
Then, Yang Dingtian was shocked to see the heavy water layer of the Yin Yang Mirror above his head suddenly fall.
That's right, the entire Yin Yang Mirror fell directly.
Yang Dingtian flew down quickly and dodged the fall of the entire Yin Yang Mirror.
This fall lasted for half a minute.
The entire Yin Yang Mirror directly sank tens of thousands of meters.
That's right, tens of thousands of meters!
Yang Dingtian knew that he had destroyed the energy circulation balance between the Yin Yang Mirror and the depths of the earth's crust.
He collected a Profound Vein Essence, which caused the entire Yin Yang Mirror to collapse tens of thousands of meters.
Looking at the dark void that stretched for tens of thousands of miles, there were more than a hundred balls of light in the hundreds of thousands of miles.
In other words, there were hundreds of Profound Vein Essences in the entire Yin Yang Mirror, and these hundreds of Profound Vein Essences maintained the energy balance between the Yin Yang Mirror and the entire world.
Once Yang Dingtian collected all these Profound Vein Essences, the consequence would be the collapse of the entire Yin Yang Mirror, tens of thousands of miles of the Yin Yang Mirror would collapse.
When the entire Yin Yang Mirror entered another kind of balance again.
Yang Dingtian sat and floated in the air, recovering his Profound Qi. Next, he would plant this Profound Vein Essence into the soul sword.
If collecting the Profound Vein Essence was very troublesome and complicated, then planting the Profound Vein Essence into the Profound Vein was undoubtedly no less than connecting countless capillaries together.
The difficulty and finesse of this task should be second only to carving the black vortex in the ring.
After an hour, Yang Dingtian's Profound Qi energy had completely recovered.
He took out his soul sword that was close to the Emperor rank and floated in the air.
Then, he released the Million Spirit Demon Fire and raised the temperature to the extreme.
Soon, the entire soul sword that was close to the Emperor rank began to melt!
Because this was a vacuum, and there was zero gravity.
Therefore, the soul sword that was close to the Emperor rank after melting was still intact.
This was even better. It was more convenient for him to transplant the Profound Vein Essence and carve the entire energy circulation system in the soul sword that was close to the Emperor rank. It was equivalent to the meridians of the human body.
How difficult was this?
It was to use Profound Qi energy to carve tens of thousands of channels in the interior of a treasured sword, and the largest would not be more than one-tenth of the size of a strand of hair. The smallest could not be described as an object.
There was no other way. Who asked the Profound Vein Essence that Yang Dingtian collected to be so awesome?
If it was just an ordinary Profound Vein Essence, he only needed to carve a few hundred channels.
Yang Dingtian first entered meditation. In his mind, he imagined the structure of this soul sword that was close to the Emperor rank. Then, he constructed the three-dimensional blueprint of the channel in meditation.
Moreover, Queen Poissa helped to perfect it, preserving the most minute structure.
This, this was really an incomparably complicated process.
However, it was still not as complicated as carving the dark vortex.
Fortunately, time could be slowed down many times in the meditation space.
In the meditation space, Yang Dingtian and Queen Poissa did not sleep or rest. It took them more than a month to completely construct the internal meridian system of the entire soul sword.
This work was too meticulous, and it was not purely energy. It also involved real matter.
Therefore, there were as many as eight failures along the way.
Of course, a month in the meditation space was only a day in reality.
Once the design of the internal structure was completed, the rest of the process became simple.
Strictly according to the structure in his mind, Yang Dingtian's Profound Fire energy quickly completed the carving in the soul sword that was close to the Emperor rank.
This work was actually very similar to the carving of circuit boards on modern earth.
"Whoosh whoosh whoosh whoosh whoosh …"
Profound Qi energy and Profound Fire energy quickly flowed in the soul sword that was close to the Emperor rank.
One must know that these channels were completely connected. The entrance was at the sword hilt, which was the place where the Sea Spirit Crystal would be placed in the future. It was equivalent to the Sea of Qi.
And the entrance was at the tip of the sword.
The Profound Fire energy first carved a main energy meridian in the soul sword.
Then, it quickly dispersed into four energy and began to carve the branch meridian.
Then, it divided into eight, sixteen!
In the end, it was completely hundreds of energy, operating together and carving in the soul sword.
This was actually very similar to a programming system. First, a framework was designed, and then it would run automatically.
Speaking of which, it was all thanks to Yang Dingtian's comprehension of the Divine Realm.
Otherwise, he would have to honestly carve a Profound Fire energy from the beginning to the end. This would take several months to complete.
One must know that at that time, his master, Dongfang Minmie, only had a few hundred channels of the soul sword meridian. It took him ten days and ten nights to complete.
After Yang Dingtian designed the meridian framework, he used the martial arts civilization code to write a simple energy scroll. Then, the energy scroll would automatically control the circulation of the Profound Fire and Profound Qi energy.
In this way, Yang Dingtian only needed to be responsible for the output of the Profound Fire and Profound Qi. The rest would be completed automatically. And it would be 100% accurate. There would be no error, and there would not be a situation of failure.
In this way, Yang Dingtian completed all the tasks that would take several months in just half a day.
The carving of the internal meridian system of the soul sword had been completed.
Next was the last step, which was to transplant the Profound Meridian Essence into the meridian system of the soul sword.
This should be the most difficult and tiring step.
Yang Dingtian took a deep breath. He did not rest but wanted to do it in one go.
Unfortunately, he could not write an energy scroll to transplant the Profound Meridian Essence. Otherwise, it would be simple.
Of course, the scroll was easy to write.
But the key was to control the Profound Qi and pick up each strand of Profound Meridian Essence. This was too difficult and required manpower. The scroll could not be completed.
Therefore, Yang Dingtian had to be honest and transplant each strand of Profound Meridian Essence into the soul sword.
Closing his eyes, he calmed himself down for a moment and gathered all his energy.
Next, Yang Dingtian began the rapid process again.
He began to transplant the entire Profound Meridian Essence.
First, it was the main meridian. This was very simple.
Next, it was the branch meridian. Next, it was the branch meridian.
Yang Dingtian's movements were very, very fast. But no matter how fast he was, it still took one or two seconds to transplant one strand.
And he could not make any mistakes. If he made a mistake, he would have to repeat all the steps in this step.
Just like this, time flew by quickly.
Two hours passed, four hours passed …
A full day and night passed.
Yang Dingtian finally transplanted the last strand of Profound Meridian Essence into the soul sword.
Finally, he suddenly transplanted the Millennium Owl's demon core into the sword hilt.
"Whoosh …" An ice-cold Xuan Qi swept past.
The soul sword that was close to the Emperor grade suddenly froze!
It's done, it's done …
Yang Dingtian was on the verge of tears. He had spent the entire day and night concentrating his mind and transplanting the strands one by one. He was truly on the verge of collapse. He had never completed such a complicated and terrifying task before.
Now, it was finally done.
Yang Dingtian almost collapsed to the ground and then slept for a few days and nights.
However, he could not sleep yet.
At this time, the soul sword was already mostly completed.
The only thing missing was the Sea of Qi. But the Millennium Owl's demon core could barely be used as a small Sea of Qi. It could barely store some Profound Qi.
Holding the soul sword that was close to the Emperor grade in his hand, Yang Dingtian could clearly feel the huge changes.
First of all, this treasure sword was no longer golden. Instead, it was faintly transparent. Inside, it was flowing with brilliant colors.
Next, he had to try and see if he could summon the sword spirit!
Yes, it was the sword spirit!
